Device of little sample of preparation X ray nanometer CT metal based on local electrochemical etching

The utility model discloses a because the device of the little sample of local electrochemical etching's preparation nanometer CT metal, including accurate position control unit, electrochemical etching unit, real time monitoring unit, accurate position control unit is used for the translation of sample, the electrochemical etching unit be used for accurate sculpture sample, obtain required structure, the real time monitoring unit be used for the sculpture state of in situ observation sample, and will the state gather the formation of image. The utility model discloses an electrochemistry local sculpture can convenient and fast, low -cost preparation diameter only be tens of or several microns metal microtrabeculae samples and the complicated shape little sample of dog bone shape normal position mechanical testing for example, is applicable to the preparation of the X ray nanometer CT sample of most metals or alloy, has solved the system appearance difficult problem of the three -dimensional microstructure as
